RISER-PIPE HANGER.

To all whom it may concern Be it known that I, HENRY Huron, a citizen of the United States, residing at New l T loin city, in the borough of BLOILX and State of New York, haveinvented certain new and useful Improvements in Riser- Pipe Hangers, of which the following is a clear, full, and exact description. U

My improvements relate particularly to means and devices for hanging or suspend ing riser pipes in buildings, especially dwellings, and are designed to overcome the objections and difiiculties inherent in the old method of such suspension and to afiord a simple, cheap but safe and effective suspender fulfilling all the requirements of the law, and adapted to be utilized and applied readily under the varying conditions and requirements of use.

Heretofore riser pipes have-been centralized and suspended by means of couplings or collars resting upon metallic floor plates supported on cross stringers between adjacent iioor beams, said stringers resting on cleats attached to the sides of the floor beams. The floor plates are not secured to the stringers but only rest thereon so as not to interfere with the vertical alinement of the pipe. This arrangement makes it diflicult to comply with the law that specifies a space of three fourths of an inch at least between a steam riser pipe and all woodwork. Furthermore the woodwork of the cleats and stringers dries out and shrinks very soon, loosens from the sides of the beams and allows the riser to slump or drop, resulting in all kinds of trouble and inconvenience. I obviate these difficulties by the provision and use of my riser pipe hanger consisting essentially of a pipe-encircling loop and a gravity clutch jaw pivotally and independently supported on a fulcrum rod common to both, which fulcrum rod is in turn pivotaliy supported on a suspender the upper end of which is also preferably pivotally supported substantially as herein after set forth, so that practically a universally jointed or articulated riser suspender is attained which adapts itself perfcctly and accurately to the vertical alinement of the riser pipe while supporting the same effectually and adapting itself auto matically to, and compensating for, any variation or deviation in inclination of said riser. the need for a special built up support is Specification of Letters Patent.

By the use of my riser hanger also.

obviated since the riser suspender may be supported directly upon and between adjacent beams of the flooring; and this in a convenient and expeditious manner,and it constitutes not only a permanent suspender but maybe utilized to advanta e inthe building up and assembling of the compo nent parts or pipes constituting the riser. Furthermore ample and lawful space is afforded between a steam riser and the beams, there being no intervening wood work between the latter and the pipe.

In the accompanying drawings, Figure 1, is a top view ofthe pipe loop and clutch jaw showing the riser pipe and suspender in section; Fig. 2, a vertical sectional elevation on a reduced scale illustrating the practical application and use of my riser hanger; Fig. 3, is a vertical sectional elevation on the same scale as Fig. 1, illustrating the func tion of the gravity gripping jaw; Fig, 4, is a top View of the parts shown in Fig. 2, with the riser pipe in cross section.

In the drawings 8, represents a steam riser or any other stand pipe such as used in modern buildings for various purposes, and 5, 5, the ordinary floor beams of the building, or any other stationa meansof support that may be available for the suspension'of said riser 8, from and between the several floors of the building.

The suspended member of my device is preferably made with an upper eye or loop 2, or equivalent, for the reception of a cross bar l, to rest on top of adjacent beams 5, 5, as illustrated in Figs. 2, and 4, or the suspende-r 1, may by other well known mechanical expedients be adapted for attachment to a fixed support suitably positioned with relation to the prescribed alinement of the riser 8. The lower extremity of the suspender 1, is also formed with a loop or sleeve 3, for the reception and support of the fulcrum member 6, upon which the pipe strap 7, and gripping jaw 9, are both pivot heavier the weight or strain the more surely will the grip hold. Thus in the assembling of the sections of pipe to form the riser 8,

my hanging device may be used for the temporary support of the sections, to be finally used as a permanent support for the riser when properly connected up and alined. It is thus a time-saving device during installation and an effective support thereafter.

Heretofore it has been necessary to collar the riser, either by the utilization of a coupling for the purpose, or by a separate appliance,in order to form a bearing shoulder for contacting with the upper side of the floor plate supported as heretofore stated whereas my device is adapted to grip and support the pipe anywhere of its length without the aid of shoulder or extraneous device.

hat I claim as my invention and desire to secure by Letters Patent is,

1. A riser pipe hanger of the character designated comprising a suspender member, and a pipe strap member, and clutch jaw member each independently pivotally supported upon a common fulcrum on said susponder, for the purpose described.

2. A riser hanger of the character designated comprising a suspender member pivotally supported, and a pipestrap member, and clutch jaw member each independently pivotally supported upon a common fulcrum on said Suspender, for the purpose described.

Signed at New York city, N. Y. this 25th day of October, one thousand nine hundred and thirteen.
